Producing process for alkali proof glass beads

Abstract

The present invention is production process of glass ball for producing alkali resisting glass fiber. The materials including quartzite, calcite, zirconite, rutile, fluorite, potassium nitrate, sodium carbonate and chamotte are crushed and mixed to form the mixed material; and the mixed material is smelted in natural gas burning smelting furnace with zircon corundum brick lining and further processed through cooling, clarification, ball making and annealing to produce alkali resisting glass ball with high zirconia content. The said production process has high product output, low production cost and high product quality and low power consumption, and is easy to control.

Description

technical field

[0001] The invention belongs to the production method of alkali-resistant glass spheres in the building materials industry, in particular to a process for producing high-zirconia (ZrO) 2 ) method of producing glass spheres. The glass spheres are especially suitable as a raw material for the production of alkali-resistant glass fibers. Background technique

[0002] Alkali-resistant glass fiber is the reinforcing base material for manufacturing glass fiber reinforced cement products (GRC for short). Because this product has light weight, high strength, non-combustibility, strong designability, easy molding, and long service life, the cost is much lower than that of FRP. , Magnesium cement and its long-term performance is better than that of magnesium cement. It has been widely used in construction and civil engineering at home and abroad, not only as a wall material for cold regions, but also extended to some existing product fields usually made of FRP magnes...
